Brands have been used as marks of identification in all countries and civilizations. • The branding scene below is shown on Egyptian Tomb walls dating back to 2,000 B.C.
Branding Uses a metal instrument to burn or freeze a mark on to the animal Predominantly used on cattle and horses Original use was to showownership NOT individual animal ID numbers

Angle Brand System uses two squares with one rotated an eighth of a turn p. 144
“O” on the brand is horizontal double bars “1” is vertical double bars
EarTagging Uses special pliers to attach plastic pieces with numbers on them, easy to read from front view but less permanent than some systems
Uses of Ear Tags Identification Insect control Electronic ID Information
Ear Notching Uses a special notching tool to cut out little “V” notches on animal’s ears
EAR NOTCHING Scab in 1-2 days, healed within a week
Since having 81 pigs in one litter is impossible, the 81 notch on the left ear is added as part of the litter number, if needed.
TATTOOS • Horses - Tattoos must be officially applied by certain authorized agencies for recognition by racing commissions • Tattoos are very easily altered.
TATTOOS • Tattoos do not work satisfactorily in horses under two years of age because of growth dilution and absorption of the ink. • Some tattoos fade as the horse ages. • Tattoos can be removed
Tatooing Uses a special tool called tattoo pliers to put inked numbers in ears, lips, or other locations Permanent! Simple Relatively painless
A clean ear is the first step to a successful tattoo. Clipping ears may also be necessary to avoid interference from hair.
Apply ink between the first and second ribs of the ear. The ink should thoroughly cover the skin.
Keep a firm grip on the calf or kid to avoid any movement that could cause the tongs to slip.
Sanitizing tattooing equipment is just one way to follow biosecurity protocol.
After several weeks, the tattoo should become legible as the dried ink flakes out of the calf’s or kid’s ear.
